Laptop has only a WIFI networking option and the driver is not available during install. Hence no network detect/configure and
no real outputs copied into this mail.

Boot from CD no problem at all. During install it failed to detect the IDE CDROM drive. Following hints in installation guide
and so on, I disabled DMA and this helped a bit.  Flaky detection
and mounting of CDROM drive, but errors on reading.  Using the
all-generic-ide boot option gave easy detection/mount of the CDROM drive but the same failure to read the CDROM reliably.

Errors are something like 'Media error (bad sector)', 'DriveReady SeekComplete Error', 'Buffer I/O error on device hdc', ...

Failure is not immediate.  Some small stuff seems to be read correctly
from the CDROM. From a shell (alt-f2) I can read the files on the CDROM comfortably.

Checking integrity of the CDROM fails at about 60%, always in the same file. I've checked that file's md5sum on another computer
and it is not corrupted.

The Woody installation CDs I downloaded in 2005 work fine - I can
re-install Woody whenever I want.  Hence I believe the CDROM drive
is working properly.
